A summary of the history of stone industry in Iran
In 1307, the first stone cutting machine, a kind of saws with iron blades, was designed and built to build a marble palace. This saws worked with silica powder, which is why it was known as the flower sawing and was located in the Nazi Abad area of Tehran. At the same time, Ashkuda’s company installed a similar saw for the construction of the Justice Building. The construction of the first stone mill in Iran in 1317 was started by Astan Quds Razavi in Mashhad and was launched in 1318 In the year 1320, Goldshit with his Iranian partner in Jawaryeh Tehran set up a new saw. At the same time, the Nazi Abad factory developed its own house for up to eleven devices, the shrines of the shrine of Imam Ali (AS), the shrine of Imam Hussein (AS) and the mosque of Tehran organ, including the products of the factory. In 1327, another stone unit was launched in the area of 17 Shahrivar Square (former Jaleh).
In 1328, an Iranian milling machine was installed and in 1332 a sub-Iranian machine was installed at the plant. By 1340, in all stone workshops, rock dumping from the truck was done using rollers and rollers and rock was thrown down. Until one of the rocky factories imported a gantry crane from outside the country. In 1340, the first 60-gauge quartz blade, used with quartz powder, was exploited. In the year 1342, based on a new design, a cast iron base was created for saws, and the weight system was turned into a screwdriver, which is now used as a complete complement. By the year 1343, there were a total of 10 units of stone in the country. Of these, one was in Mashhad, one in Isfahan and the rest in Tehran By the year 1345, the production of rock was the same. After that, the first saw blade working with diamond blades was bought from abroad and installed and opened the way for mass production of rocks. Although in the foreign countries, this method of rocks was roughly 15 years old. Based on the studies, the use of stone in the form of a plaque similar to today’s work in our country has been used at least since about 60 years ago, and in the previous years, the production of stone plaque was very limited.
Iran, Paradise of rock mines
Due to the diversity of geological occurrences in it and the relative humidity of different rocks because of the insignificant amount of forests and soils, the land of Iran has a high potential of decorative stones and soft and hard rocks. One of the advantages of the goddess of stone industry in Iran is the variety of mines. While in other countries such as Brazil and India, there is only a granite stone and in Italy there is only a marble quarry, but in Iran there are a variety of decorative stone mines with rich deposits. These rocks include Granite, Marmite, Chinese, Crystal, Travertine and Marble has a high color variation. Color variation is one of the effective factors in the sale of rock, so that the Indian rock industry activists are flourishing because of the variety of granite stones in Iran, which includes 28 color spectra, but it is interesting that only in the Birjand region Iran has rocks with 30 spectra Colors are being extracted. Iran is now ranked fourth in the world as the world’s fourth largest stone producer in the world after Italy, China and India. The world’s gemstone reserves amount to about 15 billion tons, including granites, marble, travertine and marble, among which the diversity of color and quality of Iran’s stones with 7.4 million tons of reserves is in the world’s first position.
